Given a level of confidence of 95% and a population standard deviation of 14, answer the following:
--------------
n = [z*s/E]^2
--------------------------
(A) What other information is necessary to find the sample size (n)?
Ans: The Margin of Error
---------
(B) Find the Maximum Error of Estimate (E) if n = 80. Show all work
Ans:
80 = [1.96*14/E]^2
------
1.96*14/E = sqrt(80)
----
E = (1.96*14)/sqrt(80)
-----
E = 3.07
